Crucial SSDShort for Solid-State Drive or Solid-State Disk, SSD is a drive that uses non-volatile memory as a means of storing and accessing data, much like computer RAM. Unlike a hard drive, an SSD has no moving parts, which gives it advantages such as accessing stored information faster, no noise, often more reliable, and consuming less power. The picture shows a Crucial SSD and is an example of an SSD.

The first SSD was implemented in IBM supercomputers in the 1970s and 1980s. They have since been drastically improved upon and offer storage capacities of over 500 GB for home computers. As the costs of SSD storage per GB have continued to decrease, these drives have become suitable replacements for a standard hard drive in desktop and laptop computers. SSDs are also a great solution for netbooks, nettops, and other applications that don't require several hundred GB of space.

Tip: An SSD may also be referred to as a flash drive, which should not be confused with a USB jump drive or Adobe Flash.
